Clostridial diseases are important causes of livestock losses in the southern Rio Grande do Sul. Since 1978 annual surveys conducted at the "Laboratório Regional de Diagnóstico" of the "Universidade Federal de Pelotas" (LRD-UFPel) have shown that clostridial diseases represent 10.40% of the bacterial diseases diagnosed in cattle and 1.65% of all diseases diagnosis in cattle over a 40-year period. The purpose of this study is to review the clinical, epidemiological and pathological aspects of the clostridial diseases diagnosed in cattle from January 1978 to December 2018 at the LRD-UFPel in the hopes that it will constitute a useful guide for field veterinary practitioners and interested farmers. We assessed and review the necropsy protocols of 6,736 cattle; these necropsies were performed either by LRD-UFPel faculty or by field veterinary practitioners; 111 outbreaks (1.65%) were diagnosed as clostridial disease, distributed as follows: 35 outbreaks of tetanus, 34 of blackleg, 23 of bacillary hemoglobinuria, 11 of malignant edema (gas gangrene), and eight of botulism. Approximately 904, from a total of 42,480 cattle at risk, died in these outbreaks. |
